PROBLEM TO BE SOLVED: To suppress occurrence of electrolytic corrosion of a bearing in a motor driven by an inverter in a PWM system.SOLUTION: An inverter-driven motor includes a stator wound with windings, a rotating body facing the stator and holding a magnet in the circumferential direction thereof, a rotor containing a shaft coupled to the rotating body, and a bearing for supporting the shaft. In the rotor, a plurality of magnetic poles are provided on the inner periphery thereof, a plurality of plate-like bodies are laminated, and an extension part bent so that at least one plate-like body including the outermost layer among the plurality of plate-like bodies becomes practically parallel with the magnet is formed at the inner peripheral end of the magnetic pole. |
